To afZZ whom it may concern: I

Be it known that I, BURT J. WOLFE, a citizen of the United States, residing at Canton,

in the county of Stark and State of Ohio, have invented certain new and .useful Improve-- ments in Window-Screens; and Ido hereby declare that the following is a full, clear, and exact description of the same, referencebe- 1ng had to the annexed drawings, making a part of this specification, and, to vthe letters of reference marked thereon, in which- Figure 1, is a side elevation, showing the wlndow closed. Fig. 2, is a side elevation,

showing the lower sash elevatedand the screen-f in position to properly screen the window. Fig. 3, is a viewof the roller bracket, designed and calculated for journaling' both rollers. Flg.- 4, is an end view/of the cap. Fig. 5, is a view, showing a portion of the roller. and screen cover.

Fig. 9, is an enlarged v1ew of the bottom sash-bar, showing the screen holding bars, placed in proper po# sitionto connect the top or upper end of the Fig. 10, is a transversesection of the Window sashes, showing the lower sash elevatedl and the screen exposed for use, also showin g transverse section of the rollers. Fig. 1l, is a transverse section, showing the lowerV sash brought down, and illustrating the screen concealed. Fig. 12, is a detached view of the screen roller, showing parts broken away,`to illustrate the actuating spring.

The present invention has relation to window screens, and it consists in the dierent parts and combination of parts hereinafter described, and particularly pointed out in the claims.

proper.

window sashes together with their glass are operated in the ordinary manner.

The roller Vbrackets B and C, are attached to the bottom of the window frame, and are located on the top or upper side of the window ledge or shelf. To the brackets B and 0, is'attached the screen roller D, whichscreen roller is constructed in substantially the same manner as Window curtain rollers, having an actuating spring located within the roller The bracket C,is provided with the slot c, which slot is formed open, as ,illustrated in Fig. 6, and is so formed for the purpose of providing'a means for easily attaching and detaching the rollerD, together with its screen.

The roller D, is provided with the actuating spring d, which actuating spring is attached at one end to the block or head d', and its ppposite end attached to the bar cl2, and is so attached for the purpose of giving tension to the spring, as the gauze or netting E, is unwound from the roller D, thereby bringing the spring into proper condition to rotate the roller D, and wind the gauze or netting E as the sash b is lowered.

For the purpose of properly 'guiding and 'spreading Vthe gauze or netting E, as it is wound and unwound upon and from the rollerl D, the guide4 roller F, is provided, which guide roller'is journaled to the brackets B and C.

For the' purpose of changing the length of sized windows, or in other words,"windows having dierent widths. y

For the purpose of protecting the gauze or netting, and the different rollers, the cap or covering G, is provided, which cap or covering is preferably formed of polished sheet metal. For the purpose of adjusting the length of -the guide roller F, said roller is formed in IOC the cap or covering G, one end of said cap or covering is provided with the sliding extension H, which sliding extension is provided with the handle or pin g. The brackets B and C, are each provided with the grooves g and g2, which grooves are for the purpose of receiving and holding the cap or cover G, and the sliding extension H.

For the purpose of preventing the cap or cover G from becoming accidentally displaced, the upper flange of the groove g2, is provided with the recess or notch g3, which notch or recess receives the handle or pin g, substantially as shown in Figs. l and 2.

For the purpose of holding the gauze or netting in proper position during the time the sash is elevated, and at the same time closing the space, between the window strips and the edges of the gauze or netting, the grooved guides h are provided, and are 1ocated substantially as illustrated in Figs. 1, 2, 10, 11, and 8, and are securely attached to the strips h or their equivalents. The grooved guides h, are preferably formedof sheet metal, and are bentor folded to form the groove.

For the purpose of providing a means for easily attaching and detaching the gauze or netting to and from the window sash, the top or upper end of the gauze or netting is provided with the hooked bar lo, which hooked bar forms a proper binding for the raw end ofV the gauze. To the bottom or lower end of the lower sash, is attached the hooked bar k which hooked bar receives and holds the bar 7c, substantially as illustrated in Fig. 9.

For the purpose of providing a means for easily removing the bar 7c, from the bar la', the handle k2 is provided,which handle is attached to the bar la. When it is desired to detach the gauze or netting E,Erom the sash, the hooked bar 7c is lifted out of the hooked bar k', after which the gauze is wound upon the rollei` D independent of the movement of the sash.

For the purpose of providing a means for removing the hooked bar from the grooved guides h, said grooved guides are provided with the notches h2.

It will be understood that by my peculiar arrangement, I am enabled to easily detach the gauze or netting from the window sash, after which said sash is free to be operated without operating the gauze or netting.

Another advantage in removably attaching the gauze or netting to the sash, is to provide for elevating the lower sash independent of the gauze so as to easily operate shutters that may be located upon the outside of the window.

I have shown my invention as applied to the lower sash, but it will be understood that it may be applied to the top or upper end of the window frame, and to the upper sash, without departing from the nature of my invention.

For the purpose of providing the proper adjustment for the roller D, its jcurnaled end may be provided with the sliding tube D.

Itwvill be understood that the gauze or netting E, may be formed of cloth or'wire as desired.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

rlhe combination of a window frame, the brackets B andV C, the bracket C provided with the slot c, the roller D, journaled to the brackets and provided with the block or head d', and the actuating spring d, the guide roller F, formed in sections, and provided with the springf, the cap or cover G provided with the sliding extensions II, having the handle or pin g, the grooves g and g2, formed in the brackets B and C, the gauze or netting Iixed to the roller D, and removably attached to the window sash, the grooved guides h, provided with the notches h2, and the bars lo and 7c', substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence ot' two Witnesses.
